Elaphoglossum aubertii (Desv.) Moore, Ind. Fil. 5. 1857. 



North Nyasa District: Nyika Plateau, terrestrial in montane forest, 30-40

Mlanje District: Mlanje Mountain, massed on exposed branches of a tall 

 Widdringtonia tree, 20-50 cm. high, leaves stiff, coriaceous. An aggregate pan- 

 tropical species. The rhizome scales of this specimen are narrower than in the 

 typical form from St. Helena but in other respects there is general agreement. 



Elaphoglossum hybridum (Bory) Moore, Ind. Fil. 10. 1857.

 leaves sub-pendent, sterile ones up to more or less 60 cm. long, 1500 m., June 7, 

 1946, 16302. Mlanje District: Mlanje Mountain, frequent on lower trunks of forest 

 trees, about 40 cm. high, leaves more or less fleshy, only one fertile plant found, 

 1820 m., July 5, 1946, 16662*. Brass 16302 is a particularly large and robust 

 specimen resembling forms from the Comoros and Madagascar. Tropical east 

 Africa, South Africa, tropical America. 



Elaphoglossum spathulatum (Bory) Moore, Ind. Fil. 14. 1857. 

 E. ulugurense Reimers, Notizbl. Bot. Gart. Berl. 12: 80. 1934.
